DOOR.

SPECIFICATION forming part of Letters Patent No. 355,259, dated December 28, 1886.

Application filed September 2, 1886.

To all whom it may concern:

Be it known that I, LEvIS. Enos, a citizen of the United States, residing at Andover, in the county of Allegany and State of New York, have invented certain new and useful Improvements in Doors, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention has relation to certain improvements in the construction of doors, such as are used in dwelling-houses -and apartments The invention is designed to provide a door that will be light, strong, and durable, and at the same time cost less than the ordinary wooden door now in use; and it consists in securing between the side and end pieces of the door a longitudinally-corrngated sheet of thin iron, forming a single large panel, covering almost the entire surface of the door, as will be more fully hereinafter described, and particularly pointed out in the claim ap-v pended.

Referring to the accompanying drawings, which form a part of this specification, Figure 1 represents a side elevation of my improved door; Fig. 2, a longitudinal sectional view, and Fig. 3 a transverse sectional View.

Referring to these drawings by letter, A designates the side pieces of the frame of the door, and B the end pieces thereof, which may be secured together in any of the wellknown and approved ways. 1

Between these frame-pieces is securely held the thin sheet of longitudinallycorrugated metal 0, thelongitudinal edges of which rest in grooves in the inner edges of the side pieces of the frame, as will be seen by reference to Fig. 3 of the drawings. By thus securing the longitudinal edges of the corrugated metal sheet in grooves in the side pieces of the doorframe it is securely held in place, and will avoid the necessity of grooving the inner edges of the end pieces to hold the curved ends of the metal sheet, which would otherwise be necessary.

It will be observed that I do not seat the upper and lower waved or corrugated ends of the panel into the end pieces of the rigid doorframe, for the reason that this would not al- Serial No. 212,538. (No model.)

low a free lateral expansion and contraction of the panel without disjointing or breaking the frame. The upper and lower ends of the panel Omerely abut-snugly against the inner edges of-the said end pieces, so thatsaid ends can creep on the edges of the frame-pieces during expansion and contraction. Furthermore, if the said ends of the panel were fitted into grooves in the end pieces of the doorframe, the grooves would have to be sinuous to conform to the corrugations of the panel, which would involve considerable expense and labor.

The sheet-metal plates may be rolled out of malleable iron to the required size to enable them to be immediately secured into the doorframes, and thus entail but slight expense.

A further advantage of this improved door is that it will be very strong, will last a great length of time, and may be polished or other- 0 wise ornamented, so as to present a highly attractive and pleasing appearance to the eye.

I am aware that it is not new to use sheet metal in the manufacture of doors; and I therefore do not broadly claimjthe use of 5 such material, the essential feature of my invention being the longitudinally-corrugated sheet-metal panel secured in the frame of an ordinary door.

Another important and desirable feature of this invention is that the shrinkage and warping common to all wooden doors is entirely obviated.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

The within-described improved article of manufacture, consisting of a rigid door-frame having a metal corrugated panel, the straight edges thereof being let into grooves in the 0 vertical portions of said frame, and the sinuous ends abutting flu sh against the inner edges of the end pieces of the frame, substantially as described.

In testimony whereof I affix my signature in 5 presence of two witnesses. I

LEVI S. ENOS.
